The degree of the least polynomial of a square matr ix A, and henee its rank, is the number of linearly independent rows in A. A linearly independent row of A is a row that eannot be obtained from any other row in A by multiplieation by a number. If matrix A has, as its elements, the eoeffieients of a set of simultaneous nonhomo-geneous equations, the rank k is the number of independent equations. If A = , there are the same number of independent equations as unknowns A has an inverse and a unique solution set exists. If k < n, the number of independent equations is less than the number of unknowns A does not have an inverse and no unique solution set exists. The matrix A is square, henee k > n is not possible. 

As a single equation with three variables, equation 6.26 does not have a unique solution for the concentrations of CHaCOOH, CHaCOQ-, and HaO+. At constant temperature, different solutions of acetic acid may have different values for [HaO+], [CHaCOQ-] and [CHaCOOH], but will always have the same value ofiQ. 

Equation 7.8 does not have a unique solution because different combinations of and give the same overall error. The choice of how many samples to collect and how many times each sample should be analyzed is determined by other concerns, such as the cost of collecting and analyzing samples, and the amount of available sample.

Steps 6 and 7 ate involved with inputting additional specifications about the process being simulated. It is necessary to give an adequate number of specifications for each unit operation, for each calculation unit, and for the overall process flow so that all the degrees of freedom ate taken away and a unique solution can be obtained from the simulator. On the other hand, if mote than the necessary number of specifications ate given, the problem becomes overconstrained for the simulator and no solution can exist.
